ON A COLLECTION OF BUTTERFLIES MADE IN THE MAPUTA 
DISTRICT, PORT. S.E. AFRICA, BY Dr. H. G. BREYER, 
DIRECTOR OF THE TRANSVAAL MUSEUM, DURING THE 
MONTH OF JUNE, 1914. 
By C. J. Swierstra, F.E.S., etc., First Assistant. 
The butterflies enumerated in. this list were procured by Dr. H. G-. Breyer 
whilst on a conjoint expedition of the Transvaal Museum, Pretoria, and 
the Provincial Museum, Lourenco Marques. Although the chief object 
cf this expedition was large game, Dr. Breyer succeeded in obtaining a 
fair number of several species of Lepidoptera — Rhopalocera. 
The weather had been dry, no rain was experienced, and the ordinary 
winter conditions had already set in. The last rains must have occurred 
about ten days or so before the arrival of the expedition, which explains 
the fact that a large number of the species captured are repre- 
sented by summer- intermediate- and dry-phase forms. In a few cases, 
T. auxo, f.i., the whiter form only was met with. That the summer forms 
were speedily disappearing is evident by the worn condition of some of 
the specimens, although in some cases the same worn condition is a feature 
of the specimens of the dry phase. This might be attributed to the very 
bushy nature of the country; one may at least assume that specimens 
living in such country are more apt to damage themselves than in the 
case of specimens frequenting perfect open country. In a few instances, 
amongst others, T. wallengrenii Butl., two of the specimens, which are in 
a perfect condition, are distinct forms of the wet phase, but already show, 
in a few minor points, the influence of the dry season. None of the 
specimens, however, show the very bright colouration, as is usually met 
with in specimens caught during the height of and at the end of a favour- 
able summer season with plenty of rain and bright sunny days, and, for 
one acquainted with the influence the amount of rain during a season 
exercises on the production of the several forms of a species, and especially 
so in the Acraeinae and Teracoli, it is not difficult to conclude from this 
series that the summer rains have not been too plentiful, and more par- 
ticularly so one and perhaps two months before those specimens were 
caught.
